New Technical Brief on Explosion, Fireball and Pool Fire Threats from Ignited Crude Oil

By Anthony Kimery, Editor-in-Chief, 01/21/2015

In a follow-up to AristaTek’s January 2014 technical brief, Toxic Consequences of Smoke Plumes from Crude Oil Fires, that was prepared in response to the threat of an accident involving crude oil shipments, the company has prepared a new technical brief, Hazards Associated with Spilled Crude, to help with planning and response to accidents involving crude oil by consolidating several key pieces of information important to planners and responders.

A leading provider of hazardous materials planning and response solutions, AristaTek’s new brief to be released this week details the consequences of vapor cloud explosions, fireballs and pool fires for various quantities of spilled crude oil. AristaTek makes its technical briefings available at no cost to hazmat teams, fire departments, fire marshals, sheriffs, first responders and emergency response officials and any other public safety and health professionals to assist in their responsibility to protect their communities.

“We decided to do another tech brief on crude oil as there have been several articles lately about communities having done studies which show themselves to be largely unprepared for a disaster involving crude oil,” Homeland Security Today was told by AristaTek spokesman C. Scott Bunning. “Our brief provides a ‘Hazard Table’ for explosive and burn effects of both fireballs and pool fires for various along with other consolidated info we hope responders and planners will find as a useful resource.”

“During a train derailment involving crude oil, the immediate threats that responders worry about the most are the vapor cloud explosions and pool fires,” said AristaTek CEO Bruce King. “We felt analyzing these threats and providing an easy to follow table for various quantities of spilled crude would be a useful resource for planners and responders alike.”

“According to the American Association of Railroads, there were 362,000 carloads of crude oil shipped in the first three quarters of 2014,” the company said, pointing out that, “This amount is twice that of the same time period only two short years ago in 2012. Several high-profile accidents in 2013 highlighted the inherent dangers this substance can present to communities. Many states have conducted recent surveys of their response capabilities for accidents involving spilled crude and have found their responders largely unprepared for a large accident involving the substance.”

“A typical tank car may contain 30,000 gallons of crude oil, and could be part of a unit train containing over 100 tank cars. The most common accident is a train derailment, which may or may not result in a rupture spilling crude oil,” the brief says. And, “Because of its flammable nature, the crude may ignite resulting in explosions, fireball and pool fire. Multiple rail cars may be involved. The fire will also produce a dense black smoke cloud which could require evacuations or shelter -in-lace. There may be environmental concerns because of spills into a waterways.”

AristaTek said, “Crude oil presents several hazards when it is spilled in the environment and [its new technical brief] summarizes these hazards in a useful table. The first hazards happen when the spilled crude vaporizes, contacts an ignition source, explodes and also rapidly burns in a fireball. The resulting hazards are an explosion who blast is measured in overpressure, and the fireball which has a burn hazard for those standing too close.”

“The other hazard,” the firm said, “is a burn hazard associated with burning pool of spilled crude. The table offers safe-standoff distances for various quantities of spilled crude for all three hazards. The brief also offers some highlights of the recently issued industry reports on Bakken crude oil detailing characteristics of this type of crude and its lower flash point, and points out several government and industry sources for response information and protocols for emergency response.”

“The table of hazards was prepared using our flagship PEAC-WMD software, the world’s leading hazardous materials technical reference and modeling software,” King said. “Preparing this table and the brief overall is one of our efforts to provide a free but effective resource for those planners and responders attempting to prepare for this threat that isn’t going away any time soon despite the recent drop in oil prices.”

Minnesota towns talking about dangerous rail crossings

[Editor:  The Minnesota Dept. of Transportation’s study of rail crossings and bridges identified and prioritized safety upgrades all over the state, and now has towns large and small reflecting on the bomb train threats in their midst.  This is the story from one such town, Detroit Lakes, population around 8500.  A similar study here in California would go far to wake up communities all along the rails.  – RS]

 Detroit Lakes in the Bakken oil danger zone

By DL News Staff, Jan 17, 2015

Forty to 44 trainloads a week of highly volatile Bakken crude oil come through Detroit Lakes via the Burlington Northern Santa Fe rail corridor, each one a potential inferno if it derails and explodes.

Train collisions with trucks and cars often cause derailments, so making crossings safer is key to preventing a disaster such as the one that killed 47 people when a parked train rolled downhill and derailed in Lac Megantic, Quebec, in July 2013.

That’s why the Minnesota Department of Transportation assessed all rail crossings on routes that carry Bakken oil, and prioritized the potential danger and need for improvements at each one.

The bad news is that the Washington Avenue crossing is the third highest priority crossing in the state, based on population living within a half-mile of the crossing, the number and type of vehicles that use the crossing, the accident history there, and its proximity to emergency services such as the fire hall, police station and hospital, among other factors.

The good news is that the crossing has gates and medians and is already considered as safe as a crossing can be, so no additional improvements are recommended.

When the city implemented a “no-train-horn” policy on the BNSF corridor a few years ago, it was required to implement top-of-the-line safety improvements at the crossings.

Compare that to the Sixth Street N.W.  crossing in Perham, which is the second-highest priority crossing in the state. It has gates, but the state is recommending a grade separation (an underpass or an overpass) be built at that site in the long term.

Same goes for the No. 1 priority crossing in the state, the 14th Street S. crossing in Benson. It has gates and cants, but grade separation is recommended.

In Detroit Lakes, the crossings at County Road 54 (the Hidden Hills Road) and the Brandy Lake crossing near Walmart did not make the list of priority crossings.

Both were improved earlier as part of the “whistle-free zone” initiative.

The Canadian Pacific crossing on Legion Road near Snappy Park now has no gates at all, only crossbucks, but gates are set to be installed there in the next few years.

The Canadian Pacific route through Detroit Lakes (including WE Fest) Callaway, Ogema, and Waubun is not considered a Bakken crude route for the purposes of the state study, though trains do carry oil cars on those tracks.

The BNSF crossing on Lake Street N. in Frazee is No. 29 on the state’s list of dangerous crossings. It has gates, but the crossing is listed as “adequate, but improvable” in the state study.

The Fifth Street W. crossing in Frazee is No. 36 on the priority list and the state recommends medians be installed as part of a long-term solution.

The Fourth Street crossing in Audubon is ranked No. 57 on the priority list, but the crossing is considered adequate and no improvements are recommended.

No crossings in Lake Park made the list.

Other crossings on the priority list include several in Wadena, New York Mills, Perham, Glyndon and Dilworth.

Minnesota doesn’t have any control over the type of rail traffic that moves across state lines, but it’s encouraging that it has been as proactive as possible in identifying dangerous crossings and recommending solutions.

Pacific Northwest ports wary of crude by rail – Association to issue position paper

Portland port passes on oil-by-rail terminal

While Vancouver pursues project, other Northwest ports aren’t so sure

By Aaron Corvin, January 18, 2015

At one point, the Port of Portland considered a vacant swath of land (pictured above between the rail tracks and water) near its Terminal 6 as a potential site for an oil-by-rail terminal. Instead, the undeveloped tract is now under consideration for a propane export terminal. (Bruce Forester/Port of Portland)

photoThe nation’s public ports, focused on attracting industry and jobs, are largely known as agnostics when it comes to pursuing the commodities they handle.

It doesn’t matter if the shipments are toxic or nontoxic. Ports move cargoes, the story goes. They don’t pronounce moral judgments about them.

However, at least one line of business is no longer necessarily a lock, at least in the Northwest: the transportation of crude oil by rail.

Public concerns about everything from explosive oil-train derailments and crude spills to greenhouse gas emissions and the future of life on the planet are part of the reason why.

In at least two cases in Oregon and Washington, ports decided safety and environmental concerns loomed large enough for them to step back from oil transport. The Port of Portland, for example, eyed as much as $6 million in new annual revenue when it mulled siting an oil-train export terminal, documents obtained by The Columbian show. Ultimately, Oregon’s largest port scrapped the idea because of rail safety and other worries. At one point, it also reckoned that “the public does not readily differentiate between our direct contribution to climate change and actions we enable.”

In Washington, the Port of Olympia adopted a resolution raising multiple safety, environmental and economic concerns. It noted the July 6, 2013, fiery oil-train accident in Lac Megantic, Quebec, which killed 47 people. And the resolution called on the Port of Grays Harbor to rethink opening its doors to three proposed oil-by-rail transfer terminals.

To be sure, there doesn’t appear to be a groundswell of Northwest ports swearing off oil or other energy projects. Yet public concerns aren’t lost on the port industry. Eric Johnson, executive director of the Washington Public Ports Association, said he worries that putting certain commodities such as coal under “cradle-to-grave” environmental analyses sets a bad precedent that could gum up the quest for other port cargoes.

Nevertheless, he said, “we’re concerned about oil-by-rail transportation.” So much so, the association, which represents some 64 ports in Washington, will soon issue a position paper, Johnson said. It will include calls on the federal government to boost the safety of tank cars, and to upgrade oil-spill prevention and response measures. Last week, the National Transportation Safety Board said that assuring the safety of oil shipments by rail would be one of its top priorities for the year.

In Vancouver, meanwhile, critics pressure port commissioners to cancel a lease to build what would be the nation’s largest oil-by-rail transfer operation. Under the contract, Tesoro Corp., a petroleum refiner, and Savage Companies, a transportation company, want to build a terminal capable of receiving an average of 360,000 barrels of crude per day.

In addition to the political pressure, legal challenges dog the project, too. One lawsuit goes to the heart of how ports relate to their constituencies: It accuses Vancouver port commissioners of using multiple closed-door meetings to illegally exclude people from their discussions of the lease proposal.

The port denies the allegations. It has repeatedly said public safety remains its top concern. And it has said the oil terminal won’t get built unless the companies’ proposal wins state-level safety and environmental approvals.

Yet opponents see increased public attention to the safety and environmental impacts of proposed oil and coal terminals as reason to believe ports can no longer easily don the robes of an agnostic. “People are paying attention,” said Brett VandenHeuvel, executive director of Columbia Riverkeeper, one of three environmental groups pressing legal complaints against the Port of Vancouver. “It’s no longer simply the bottom line and the most revenue.”

In the Northwest, the Port of Portland’s decision to temporarily back off oil transport sharply contrasts with the Port of Vancouver’s choice to pursue it. Oil terminal critics use Portland’s decision to hammer the Port of Vancouver.

“I don’t see how an oil terminal is unsafe on the Oregon side of the Columbia (River) and safe on the Washington side,” VandenHeuvel said. “The striking thing is how close in proximity the ports of Portland and Vancouver are and the different approach they’ve taken on oil.”

In an email to The Columbian, Abbi Russell, a spokeswoman for the Port of Vancouver, said the port moves “forward on projects we think have merit and will bring benefit to the port and our community.” She also said the port understands that “every port needs to make decisions that make sense for them.”

‘Protests may occur’

Initially, an oil-train operation made sense to the Port of Portland, too.

It considered three sites: Terminals 4, 5 and 6. It analyzed the production of crude from the Bakken shale formation in the Midwest and from oil sands in Canada. It assessed business risks, including Kinder Morgan’s plan to repurpose an existing natural gas pipeline to connect West Texas crude to Southern California. And it contemplated the “primary specific concern among governments and community groups” over the potential for “oil spills, whether from unit trains, pipelines from the unit trains to the storage tanks to the dock, and barges.”

In May 2013 — about a month after Tesoro and Savage announced their oil terminal proposal in Vancouver — the Port of Portland signed a nondisclosure agreement with an unspecified company (the port redacted its identity in documents) to explore locating an oil export facility near Terminal 6.

Just shy of a year later, however, the port backed away.

In March 2014, it publicly announced that while it was “interested in being part of an American energy renaissance brought on by this remarkable domestic oil transformation” it did not “believe that we have sufficient answers to the important questions regarding environmental and physical safety to proceed with any type of development at this time.”

In an email to The Columbian, Kama Simonds, a spokeswoman for the Port of Portland, said “rail car safety was the primary issue” that led the port to temporarily halt its pursuit of an oil-train terminal.

But the port also worried about damaging “our hard-won positive environmental reputation,” documents show, and noted “other relationships will be affected,” including “other governments, neighborhood associations and civic groups …”

“National environmental groups will be involved — Sierra Club, Bill McKibben’s 350.org, Greenpeace,” it also noted. “Protests may occur.”

And the Port of Portland was aware of the controversy that engulfed its neighbor, remarking that “as seen with the Tesoro project at the Port of Vancouver and other energy-related projects at several other ports on the river system and along the coastline, these kinds of announcements can quickly create opposition, controversy and protests.”

Unlike the Port of Vancouver, whose three commissioners are elected by Clark County voters, the Port of Portland’s nine commissioners are appointed by Oregon’s governor and ratified by the state Senate.

The Port of Portland’s Simonds said Gov. John Kitzhaber wasn’t kept informed of the port’s initial pursuit of an oil-by-rail facility and that “we are not aware of any formal statement issued to the port from the governor’s office.”

Nowadays, she said, the port pursues “other energy-related projects” and focuses on Canadian company Pembina Pipeline’s plan to build a propane export facility near Terminal 6. Propane would be brought to the facility by train and eventually shipped overseas. The propane terminal would use the same property that the Port of Portland had considered for an oil-by-rail transfer operation. That project is also expected to face opposition from environmental groups.

Josh Thomas, a spokesman for the Port of Portland, said the port is “extremely discerning” when thinking about energy-sector opportunities. After rejecting coal and temporarily halting oil, he said, the port is now working with Pembina. “Propane has an excellent track record as a clean and safe alternative fuel,” Thomas said, “with a good climate story, displacing many dirtier traditional fuels.”

‘We are not alone’

If the Port of Portland only temporarily dropped the idea of an oil-train venture, the Port of Olympia in Washington went further.

In August 2014, the Olympia port commission voted 2-1 to approve a resolution expressing “deep concern” about the threat to “life, safety, the environment and economic development” of hauling Bakken crude by train “through our county.”

The resolution urged the Port of Grays Harbor — some 50 miles west of the Port of Olympia — to reconsider allowing three proposed oil-transfer terminals. It also called on the city of Hoquiam to reject construction permits for the projects.

The Olympia port’s resolution didn’t sit well with the executive committee of the Washington Public Ports Association. The committee shot a letter — signed by five port commissioners, including Port of Vancouver Commissioner Jerry Oliver — to Port of Olympia Commissioner George Barner. The letter chastised the resolution as meddling in another port’s lawful business. “We can only presume that if another port were to do this to the Port of Olympia that you would be rightly, and deeply, offended,” according to the letter, signed by Oliver, Port of Seattle Commissioner Tom Albro, Port of Benton Commissioner Roy Keck, Port of Everett Commissioner Troy McClelland and Port of Chelan County Commissioner JC Baldwin.

Barner and his colleague, Port of Olympia Commissioner Sue Gunn, who cast the other “yes” vote for the resolution, returned fire with a letter of their own. “As public officials, we have a responsibility to protect our citizenry and our natural resources,” they wrote in their letter addressed to Albro. “We are not alone in our concern over the passage of crude oil by rail through our community, as no less than sixteen other jurisdictions have passed similar resolutions, including the cities of Anacortes, Aberdeen, Auburn, Bellingham, Chehalis, Edmonds, Hoquiam, Kent, Mukilteo, Seattle, Spokane, Vancouver, and Westport; King and Whatcom Counties, and the Columbia River Gorge Commission.”

The jousting letters illustrate that not all ports think alike when it comes to how they do business.

Although the Port of Portland didn’t join the Port of Vancouver in seeking a share of the vast quantity of crude coming onto the nation’s rails, there appears to be no acrimony between them.

Shortly before the Port of Portland said last March that it wasn’t going after an oil-by-rail project, it gave the Port of Vancouver a heads-up about it.

“We wanted to make sure you had visibility to it prior to its release as the port is effectively making and taking a public position on crude-by-rail,” Sam Ruda, chief commercial officer for the Port of Portland, wrote in an email to Port of Vancouver CEO Todd Coleman and Chief Marketing/Sales Officer Alastair Smith.

Ruda offered to discuss the matter with them.

“I am doing this on behalf of Bill Wyatt (the Port of Portland’s executive director) who is traveling in Vietnam,” Ruda wrote in his Feb. 28, 2014 email. “At the same time, I have been very involved in this matter and am prepared to offer you perspectives and context as to why we are doing this at this time.”

Russell, the spokeswoman for the Port of Vancouver, said Coleman and Smith thanked Ruda for the heads-up when they later spoke with him. “These types of courtesy communications are common,” she said. “There was no additional discussion related to the statement.”

KFBK News Radio: How safe is Sacramento?

Part 1: How Safe is Sacramento When it Comes to Crude-by-Rail?

By Kaitlin Lewis, January 16, 2015


Two different railroad companies transport volatile crude oil to or through Sacramento a few times a month. The trains pass through Truckee, Colfax, Roseville, Sacramento and Davis before reaching a stop in Benicia. Last week, a train carrying the chemical Toluene derailed in Antelope.

KFBK’s Tim Lantz reported that three cars overturned in the derailment. There was initially some concern about a possible Hazmat leak.

Union Pacific Railroad insists over 99 percent of hazardous rail shipments are handled safely.

Most of the oil shipped in California is extremely toxic and heavy Canadian tar sands oil, but an increasing portion of shipments are Bakken crude, which has been responsible for major explosions and fires in derailments.

Firefighters around the region are being trained on how to respond to crude oil spills.

However, Kelly Huston with the California Office of Emergency Services says 40 percent of the state’s firefighters are volunteers.

“They’re challenged right from the get-go of being able to respond to a catastrophic event like a derailment, explosion or spill of a highly volatile compound like crude oil,” Huston said.

Since 2008, crude by rail has increased by 4000 percent across the country.

By 2016, crude-by-rail shipments in California are supposed to rise by a factor of 25.

Union Pacific Railroad hosted a training session in November 2014.

Six out of the eight state fire departments listed as having completed the course confirm they were there.

“We were trained in November,” Jerry Apodaca, Captain of Sac City Fire, said.

When asked when he received the first notification of crude oil coming through, he said he didn’t have an exact date, but that it was probably a month or two prior to the training — in September or October.

Apodaca says the U.S. Department of Transportation requires railroads to notify state officials about Bakken oil shipments.

“Basically it just says in this month’s time, there should be 100,000 gallons going through your community. So it didn’t really specify when, or where, or how many cars or what it looks like,” Apodaca said.

And Paul King, rail safety chief of the California Public Utilities Commission, says it’s not easier to distinguish which lines transport Bakken oil through an online map.

“It was hard to interpret and it was too gross. Basically, the whole state of California on an 8 1/2 by 11 piece of paper with what appears to be a highlighter pen just running through the counties,” King said.

PART 2: How Sacramento’s First Responders Will Deal with Oil Spill


KFBK told you Sacramento’s firefighters were being trained on how to respond to a crude-by-rail derailment after shipments had already been going through the region in Part 1.

In Part 2, KFBK’s Kaitlin Lewis will tell you how Sacramento’s first responders will handle a possible oil spill, and what caused that train derailment along the Feather River Canyon.

It’s called a bomb train.

On July 6, 2013, 47 people were killed in Canada when a 73-car train carrying crude oil derailed.

About 30 buildings in the  Lac-Mégantic downtown district were destroyed. The fire burned for 36 hours.

“If we have a derailment and fire of crude oil, fire departments are going to throw large quantities of water and foam to cool the tanks and to put a blanket on the liquid that’s on the ground to help smother that fire,” Mike Richwine, assistant state fire marshal for Cal Fire, said.

Richwine says that’s the only operation for a spill/fire.

In December, 11 cars carrying corn derailed along the Feather River Canyon.

Paul King, rail safety chief of the California Public Utilities Commission reveals the cause was a rail line break.

“That was probably the most concerning accident because that just as well could have been one of the Bakken oil trains, the corn, you know, ran down the bank. It was heavy, and it consequently does put more force on the rail, but it’s about the same weight as an oil train,” King said.

Aaron Hunt, a spokesman for Union Pacific says California has more than 40 track inspectors and 470 track maintenance employees.

“In addition to that, cutting edge technology that we put in to use for track inspection. One of those technologies is our geometry car. It measures using lasers and ultrasonic waves, the space between the two rails — makes sure that space is accurate,” Hunt said.

But Kelly Huston, deputy director of California’s Office of Emergency Services says the real challenge is preparedness in remote areas like the Feather River Canyon, which is designated as a High Hazard Area due to historic derailments.

“In some more metropolitan areas, your response may be quicker and they’ll have that gear and the training and knowledge of, like, how do we fight this kind of fire? And in some areas, like in the more remote areas like we talked about in the Feather River Canyon there’s going to be perhaps maybe volunteer firefighters that have the basic equipment,” Huston said.

The Feather River feeds the California Water Project, which provides drinking water for millions of Californians. The nearest first responder is Butte County Fire Department, which is approximately 31 miles away.
